TemperatureWhat is temperature?Temperature is a degree of hotness or coldness the can be
measured using a thermometer. It's also a measure of how fast the atoms and
molecules of a substance are moving. Temperature is measured in degrees on the
Fahrenheit, Celsius, and Kelvin scales.Click Here to look at a

What is the Wind Chill
Index?The wind chill index is the
temperature your body feels when the air temperature is combined with the wind
speed. The higher the wind speed the faster exposed areas of your body lose
heat and the cooler you feel.Click

What is the Heat Index?The Heat Index is a combination of air temperature and
humidity that gives a description of how the temperature feels. This is not the
actual air temperature. Heat Stroke is the most severe form of heat injury and is
a life-threatening emergency. It is the result of long, extreme exposure to the
sun, in which a person does not sweat enough to lower body temperature. Take a
look at the chart below to see what the Heat Index needs to be for you to get
heat stroke.

How do you find the temperature for a specific
day?First, go to http://weather.gov. Then, click on the map for the place
you are looking for. After that, look for a section called Climate. Beneath
that title, read what is labeled and click on the one that most suits what you
are looking for. This should take you into the National Weather Service's
climatic data information for your specific area.

Why can you see your
breath when its cold outside?Your breath is reasonably warm and humid and it has
invisible water vapor as a large component of the gas. Warm moist air meeting
the cooler air outside the body causes the invisible water vapor to condense
the cooler air outside are visible and form the cloud that you see. The
relative humidity which depends upon water content and temperature goes to
100%. As the breath gets further from the person's face the water content
dilutes and the relative humidity goes down and the droplets go back into vapor
form.Can you tell the temperature by listening to
the chirping of a cricket?Yes! The frequency of chirping varies according to the
temperature. To get a rough estimate of the temperature in degrees Fahrenheit,
count the number of chirps in 15 seconds and then add 37. The number you get
will be an approximation of the outside temperature. Know the

WIND
CHILL ADVISORY - Issued when the wind chill temperature is forecast to be
between -15°F to -24°F.WIND CHILL WARNING - Issued when the wind chill
temperature is forecast to be -25°F or lower.

HEAT ADVISORY - Heat Index is greater than or equal
to 105°F and less than 115°F for less than 3 hours per day. Also,
nighttime heat indices should remain above 80°F for at least 2 consecutive
days. EXCESSIVE HEAT WATCH - Heat indices of 115° F
or greater may occur in the next few days.EXCESSIVE HEAT WARNING - Heat Index is 115°F or
greater for more than 3 hours per day for at least 2 consecutive
days.

Wave Safety Tips
Extremely hot weather takes a large toll on the
human body. In an average year, the summer heat in the U.S causes about 175
deaths. People most at risk for heatstroke are the elderly, small children, and
people with weight and alcohol problems. Always listen to the radio and
television for the latest information and instructions for your area.
HEAT WAVE SAFETY TIPS: Slow down! On a hot
day, dont perform strenuous activities. Dress for summer. Wear
lightweight, light-colored clothing. Drink plenty of water. Your body needs
water to keep cool. Spend more time in air-conditioned places. If you
dont have air-conditioning, then have plenty of fans. Dont get too
much sun. Heatstroke, heat exhaustion and sunstroke are possible with prolonged
exposure to the heat. If someone gets heatstroke or heat exhaustion seek medial
attention immediately.

the difference between the freezing and melting process. It allows kids to take
the temperature of a glass of snow. Then, watch the snow melt and observe how
the temperature changed. Science Fair Project Ideas: Here is a
